To all whom it DMZ/y concern:

Be it known that we, JAooB BALL, a resident of \Vaterloo, and ROBERT E.RITZ, a resident of Berlin, in the county of lVaterloo, Province ofOntario, Canada, subjects of the King of Great Britain, have inventedcertain new and useful Improvements in Calendars; and we do herebydeclare that the following is a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to new and useful improvements in what arecommonly known as perpetual calendars; and it consists incortainfeatures of novelty in the combination and arrangement of the parts andnumerals comprising such calendar whereby a series of relatively fixedand relatively movable numerals maybe so combined in one generalstructure as to provide means whereby such structure is available foruse as a calendar for a predetermined period of years as indicated bynumerals in year-charts arranged thereupon and made a part of thecalendar.

A further feature of our invention is the combination, with elementsadapted to prod uce a calendar available for use during what are hereincalled common yearsthat is, the years other than leap-years-with movableconnections whereby the same general device is adaptable for use inindicating the days of leap-year.

The object of the invention is to produce in a unitary device such acombination of parts provided with fixed and movable digits that thesame device may be utilized as a calendar for a considerable period ofyears to be de termined in advance by the limits to which the numericalarrangement is carried out.

In the annexed drawings similar characters of reference indicate likeparts in all the views where used, wherein Figure l is a general face orplan view of a calendar provided with the invention, the calendardisclosed in Fig. 1 representing the current year 1904, together withyear-charts, hereinafter described, to render the same available, inconjunction with other features subsequently developed herein, for usefor the period up to and including the year 1950 and also indicatingcalendars for the years 1850 to 1900, inclusive. 2 is a face or planview of what is hereinafter designated as a base with a slidable memberespecially available for use in or during lcap-years connectedtherewith. Fig. 3 is a detached detail view of a movable face-plateadapted to be used in conjuntion with the base of Fig. 2, upon whichface-plate are shown yearcharts. Fig. l is a sectional view taken on theline i a of Fig. 1. Fig. 5 is a section taken on line 5 5 of Fig. 1.Fig. 6 is a view taken on line 6 6 of Fig. 2, and Fig. 7 is a sectiontaken on line '7 7 of Fig. 1.

in the subjoined description of our invention certainarbitrarily-sciected titles are given to different parts for the sake ofclearness and brevity as follows: The base-sheet or major sheet, whichis shown in detail in Fig. 2 with a slidable member at the upperlefthand corner thereof, (which member is connected therewith,) ishereinafter termed in the specification and claims the base, said basecomprising the necessary digits for ten months, preferably arranged. toexhibit the necessary day-numbers for all the month-see tions from Marchto December, both inclusive, as hereinafter described. The twelve seriesof numerals shown in full in Fig. 2and partly exposed in Fig. 1, whichnumbers serve to indicate the month-days numerically and approximatelychronologically as to series of sevens, are hereinafter calledmonthcharts. The slidable member connected with said base in theexemplification of the invention shown being located at the upper lefthand portion of said base and carrying there on the necessary digits forthe days of two month-sections, as January and February, is called theslide. The outer 'or perforated face-plate shown in plan view in 3,which face-plate has shown thereon the charted arrangement of numeralsfor the several. years for which the calendar is meant to be availableand has the sight-openings to disclose the required digits for theseveral months, is called the face plate, The charted arrangement ofnumerals shown beneath the numerals 1850 to 1900 and bcneuth thonumerals 9290i to 'iSSiO uro hereinultor culled the your-M1 arts.\Yithout turthor doscription or pi! oi? dooro uorouiutter used roiercncvto tho "husof month cha s "sli1lo,

Referring now to Z 'l or detsilod description of the faceplate, it willhe noted that ited to gr! o LIL plate 1 are also provided slots 12, twoof such slots being shown, through which slots project studs or buttons13, as shown in Fig. 1, which are available for the purpose of holdingsaid face-plate 4 in position slidably upon the base 1, so thattheopenings 11 in said face-plate may be shifted longitudinally of theprojection of said slots 12 for the purpose of exposing differentseries, including portions of each month-chart, before referred to, suchexposure exhibiting only the required numerals of each month-chart forany particular month of a given year and the size and configuration ofsuch openings 11 being such as to expose only the proper numbersavailable to be utilized during any predetermined year. In addition tothe buttons 13 other buttons 14, four in number, being disclosed in Fig.1, are provided for the purpose of holding the faceplate slidablyengaged with said base and with the slots 2, before referred to, in suchbase, whereby a more perfect connection of the base and face-plate isprovided.

Year-charts.-The year-charts (designated by the letters A and B and bestshown in Figs. 1 and 3) comprise series of numbers in blocks of four,followed by a blank space where permissible, though, as disclosed, theyear-chart intended tobe available for calendar purposes from 1850 to1900 commences with and 51, followed by a blank space, after Whichappear the numerals 52, 58, 54, and on the top line of such chart,followed by a blank space on the next lower line with numerals 56 to 59,inclusive, with blank space, and the numeral 60. In the line includingthe numbers 50 to 55, inclusive, but one blank space appears. In theline including the numbers 56 to 60, inclusive, two blank spaces appear.In the next line six numbers and one blank space appear.

in the following line five numbers and two blank spaces appear, &c. Itwill be noted that the numerals commencing with 52, including eachfourth year thereafter, are shaded for the purpose of indicating thatsuch years are leap-years, and on the occurrence of such years theleap-year shift should be applied to the slide 5 to render the calendaravailable for use to correctly indicate the proper arrangement of daysand numbers for the months of January and February, though for othermonths the shift need not be made. Correspondingly the year-chart B,which includes 1901 to 1950, both inclusive, is divided into parallellines comprising the numbers serially arranged in blocks of fourfollowed by a blank space, with each fourth number shaded, commencingwith 4 and ending with 48 in the disclosure of Fig. 1. It will be notedthat in the period from 1850 to 1900 the numbers commence with 50 andend with the two ciphers, the 19 being understood, while in theyear-chart B the numbers 19 are omitted, such chart beginning with thenumber 1 and ending with the number 50. As shown in Fig. 1, as beforesuggested, the calendar is arranged for the present or current year,which is a leap-year. Hence the slide 5 is shifted, as shown in the fulllines in Fig. 2, so as to disclose the numerals Q9 through the orifices7 in said slide and also the letter L through the orifice 6 therein. Itwill also be noted thatin the slot 15 appear the letters "A. D. aboveboth charts A and B, which letters are intended as an index or gage todetermine the degree of shift which shall be imparted to the face-platein moving it over the base 1. If it is intended to render the calendaravailable for use in the year 1905, the face-plate shall be shifted, asindicated by the arrow in Fig. 1, to bring the numeral 5 under theletters A. D., whereupon, as will be evident, the first numeraldisclosed on the January month-chart would be 1, which would indicatethat the year 1905 commenced on Saturday, said numeral l being the firstnumeral on the upper line of the month series for the month of January.However, the year 1905 does" not commence on Saturday, and it will beevident that the slide 5 should be shifted to the right one notch, so asto disclose the letter C through the orifice 6, whereupon the numeral 1on the upper line will disappear beneath the face 16 of the face-plate,and the first number exposed in the opening for January Will be 1 on thesecond line of that month series, thus exposing for the month ofJanuary, 1905, four complete rows of sevens, commencing with 1 andending with 28, and also the numerals 29, 30, and 31 on the bottom rowof that series, and the other month-days will be arranged in regularorder, so as to render the calendar available for use during the year1905, which is a common year, the shifting of the slide 5 having coveredthe numerals 29, and following thenumeral 28, exposed through theface-plate, will appear the opening 7 on the lowest line, beneath whichwill be a blank space on the base. If the calendaris to be used for someother yearas, for example, 1910, which is not a leap-year-the slide 5remains in the same position as when in use for 1905, the faceplate isshifted to bring the numeral 10" below the indicating-letters "A. D.,and the first day of 1910 will be Saturday, January 1, followed by theusual numbers in series of seven for that and the succeeding months,reading vertically of the numbers exposed through the said openings 11.
